SPECIFICATION forming part of Letters Patent No. 389,804, dated September 18, 1888.

.Application filed .Tannen 5, i888.

To aZZ whom it may concern.'

Be it known that I, FREDERICK E. Geer HAUS, a citizen of the UnitedStates, residing at San Juan Mill, in the county of Bexar and State of Texas, have invented new and useful Improvements in Mowers, ofwhich the following is a specification.

This invention relates to improvements in mowers, and by means of this invention an easy working ot' the operating parts of the mower is secured. This'invention is set forth in the following specification and claims, aud illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a mower. Fig. 2 isa plan View ofa mower. Fig. 3 is a plan view of one of the cutters or knives. Fig. 4 is a plan view of the other cutter or knife. Fig. 5 is aplan View of one ofthe guide-plates.

Fig. (i is a plan View ofthe othei'gliide-plate.

Fig. .7 is avscction in the plane x fr, Fig. 2,- on a larger scale than Fig. 2. Fig. Sisaplau view of a modification on a smaller lscale than Fig. 2 and partly broken away.

Similar letters indicate corresponding parts. In the drawings, the letter-A indicates a bifureated frame-or support carrying the axle 'B of the wheel C, which is placed on its axle between the opposite sides of the frame. Pro- 3n jections D on the wheel secure revolution of the wheel when the mower is moved over the ground. `The handle E serves for the application of`power to move the device. To the wheel Gare secured the gears F. As seen in Fig. 2, the gears F are secured to opposite sides of the wheel, so that the strain of said gears is distributed equally over the wheel C. Easy working of theparts is thusseeured,and the wheel 0,' with its axle B, is not likely to t 4e be worn or inju red in consequence of any un-f equal strain. f

The gears F are adapted to 4rotate the pinions G, thereby rota*` ing the shafts l{,to which said pinions are attached. These shafts ll H, tworin number, are supported in an inclined position in opposite sides ot' the machine,their upper ends heilig journaled in bearingsll, attached to the frame A, while their lower ends arejournaled in straps or bearings ll, attached to the guideplates L, which are Serial No. 2501525. (Xnniedel.) -l 'A "w `secured lo the lower end of the bifnrcated fraaie. The pinions Gv are feathered on the shafts H,so that said piuious can be slidalong the shafts H to come into or ont of gear ,with the gears F, as may be desired.' When the pinious Gare in 'gear with the gears F, the

. cutters will operate during the motion of the device, while when the pinions are not so inc-,-

gear the cutters will not operate,`l as will preseut-ly appear. Suitable means-such as friction-collars Iserve to hol-d the pinious G in the proper position on the shafts H.

The lower ends ofthe shafts H connect by cranks or crank-pins with pitmen J, so that when the shafts H rotate a reciprocating motion is communicated tothe pitmen J. The pitmen J arepivotallyconnected to the cutters It.

K and the reciprocatingD movements of thepitmen canse the cutters to reciprocate. The cutters are made to reciprocate or work together in opposite directions, so that au effective cutting or'shearing operation results. Thecutters K are made to reciprocate getween guide plates L. The guide-plates L are held to the `frame A by screws M. passing through holes Q in the plates L and through slots N in the cutters K. vided near their rear edges with holes Q for the passage of screws M', by which they are held together. The slots N allow a reciproeating movement of the cutters. In order to steady the blades of grass4 o'r other material being cut, lingers 0 arc -applied to the lower guideplate, L, as shown. The screws M, be-

sides securing the plates L in place, can also.

be used to press the plates audthe cutters more or less closely together, as may be desired.

The feet or shoes l are used to partly snpport the frame A, and said `shoes allow the frame to glide casilyover theground. Vheels or casters can beapplied in any suitable way in place ofthe shoes l?, or, as seen in Fig. S, the slices l? can he made to support wheels R, that are journaled therein.

lhe cutter K, as seen in Fig. 2, can be made to extend from each side of the frame A, or only from one side thereof, as seen in Fig. 8. The construction shown in Fig. 8 may be'of advantage in certain localities or under cer- These gnideplates L are pro-A IOO tain conditions, since by having no ent-ter diA rectly in frontof the frame A the material being ent-Sneh,for example, as long grass-will fall to one side of the frame A and not on the frame.

What I elaim as new, and desire to secure by Letterslatent, is

1. The combination of the bilnreated frame A, the single eentrall 'arranged drivewheel no C, journaled in the frame and having at, each side an attached annular gear, F, the opposite bearings H', seenred to the inner sides of the bifnreated frame, the gnidelilates L, Se cured to the forward endet" the frame, the x5 bearing-plateslseenred on the gudeplates,

the inclined shaftsH, arranged between the sides of the bitureaied frame and jonrnaled in aid bearings, the pinions G, Capable ofbeing shifted on the shafts to mesh with the annular zo gears, the pitmen J, connected with the lower ends ef the sliafts,and the Gutters K,eonneeted with the pitmen, substantially as described.

2. 'lheeombination of a bifnreated frame, a driving-wheel, C, supported therein, gears F F, secured to opposite sides of said Whee, in 25 elined pitmen-driving shafts H 1I, carrying at therinuer ends pinons G Gto engage said gears,gnideplates L L,snpported by thelower and forward end of the frarne,cntters Klimmvided withslots N N, and supported between 3o said guide-plates, pit'men J J, connecting the Cutters and shafts. and adjusting Screws M, applied to said plates and cutters, substantially as described.

In testimony whereofl have hereunto set my 55 hand antlseal in che presence oftwo subscrib ing witnesses.
